The All-Electric Smart EQ Fortwo Cabrio
In June 2020, Smart Europe GmbH was founded, as a wholly owned subsidiary of Smart Automobile Co. Ltd. The company is a joint venture between the German automotive manufacturer Mercedes-Benz AG and Geely Automobile Co,, Ltd, the privately-owned Chinese automotive manufacturer.
The vision of the joint venture is to “position Smart as a leading provider of intelligent electric vehicles in the premium segment’. The Smart Europe based team is responsible for all sales, marketing and after-sales activities. The Smart portfolio of battery-electric vehicles (BEVs) include:
- All-electric Smart #1
- All-electric Smart #3
- Smart EQ Fortwo coupe
- Smart EQ Fortwo Cabrio
- Smart EQ Forfour
Field testing of the electric variant for the Smart Fortwo EV began in London in 2007, with 100 Smart Fortwo electric cars. Daimler has an ambition to market the Smart electric car in up to 30 global market. The EV is already available in a number of European markets and also popular with electric car sharing schemes.
The company announced the rebranding of the Smart Fortwo in 2018, with EQ included in the upgraded brand to align itself with the Mercedes-EQ branding. In 2019, the Smart EQ Fortwo was updated with a facelift.
The compact Smart EQ electric car is well suited for the urban environment, in particular, in towns and cities that are densely populated, with severe road congestion. The EV is easy to park, even in small parking spaces. Certainly easy to drive too. For individuals and families living in towns and cities, the EQ electric vehicle is a good second car, best used for shorter commutes, like school runs, trip to the grocery store, to work (if close by) etc.
The EQ EV is available in one EV battery size (17.6 kWh). Given the positioning of the pure electric car as a city car, a 17.6 kWh EV battery size is more than appropriate. Do keep in mind, the smaller the EV battery, the lower the total weight of the electric vehicle (EV), and the greater the vehicle efficiency.
The EQ EV has a claimed WLTP range up to 132 km. But of course, the electric range depends on a number of factors, to include: driving profile, road conditions, speed, weather, passenger load etc. Expect the real-world electric range to be lower than the claimed range and closer to 100 km. Nevertheless, the EV has a good electric range for everyday shorter drives, and driving a pure electric car like the EQ, will save you money and improve air quality.
The EQ electric car does not offer fast DC charging. This is not a concern, given the small size of the onboard EV battery. However, the EV does incorporate a three-phase 22 kW AC onboard charger. Given that most homes in India are powered by single-phase power supply, most of us will not be able to take advantage of the three-phase onboard charger. For this with access to three-phase (22 kW) charging at home or at work, the EV can be charged from 10% to 80% in a mere 40 minutes.
Single-phase (7.4 kW) EV charging will take longer. The EV can be charged up to 80% via a dedicated single-phase EV charger like myenergi zappi in 3 hours and 18 minutes. Though the EV can be charged via a domestic 3-PIN plug, we at e-zoomed do not encourage using a domestic plug for charging an electric car. The EV will take up to 8 hours and 30 minutes to charge up to 80% via a 3-PIN socket.
We at e-zoomed recommend charging overnight when the electricity prices are lower. We also recommend charging on a regular basis. This way charging times are reduced and regular charging is good for the long-term maintenance of the onboard EV battery. The manufacturer offers a 8 years/ 100,000 km warranty.
Standard equipment includes: central locking with radio remote control, visual locking verification and immobiliser, electronic stability programme, rear parking aid with acoustic warning and reversing camera, hill start assist, instrument display with battery charge status display and power display, smart Connect Media-System and more.
Despite all the advantages of the Smart EQ ForTwo in urban environments, the EV is limited by space and practicality. It offers a 190 L boot space, which is certainly small. Do not expect it to hold the family weekly grocery shopping! Also, it only offers two seats.
In terms of performance, the rear-wheel drive EQ electric car can achieve 0-100 km/h in 11.9 seconds (maximum power: 82 hp/ torque: 160 Nm). The top speed for the EV is 130 km/h. Of course the electric car also benefits from instant torque. The EV also offers an Eco Mode to further improve the energy efficiency of the EV.
Bottom-line, electric driving is good for the environment and the wallet! The Smart EQ Fortwo cabrio electric car is not available in India.

Benefits Of Electric Driving
The benefits of electric driving are many, with significant advantageous over petrol and diesel internal combustion (ICE) engine cars, for all stakeholders. These benefits include:
- Lower to zero-tailpipe emissions
- Lower running costs
- Lower taxes
- Lower maintenance costs
- Lower noise pollution
- Convenience of charging at home
- Smoother drive
- Instant torque for acceleration
- Lower environmental impact
Below we have highlighted three of our favourite benefits of owning and driving an electric car.
Improved Air Quality
Battery-electric vehicles (BEVs) or all-electric vehicles do not have tailpipe pollution. In fact, such electric cars do not even have a tailpipe! Zero-emission electric driving has a real and immediate impact on local air quality i.e. improving air quality.
While, plug-in hybrid electric vehicles (PHEVs) have reduced tailpipe pollution compared to traditional petrol and diesel vehicles. The sooner we migrate to electric driving in India, the sooner we can improve air quality for all our cities, towns and villages. Lower air pollution will also result in a reduced number of health issues arising from inhaling toxic pollutants.
Lower Maintenance & Running Costs
Electric vehicles (EVs) are cheaper to maintain and drive. Pure electric cars have far fewer moving parts compared to internal combustion engine (ICE) vehicles. The fewer the moving parts, the lower the probability of repair and maintenance. Moreover charging an electric car can cost as little Rs 50 per 100 kilometres! A full charge can cost between Rs 100 and Rs 200. Significantly cheaper than filling a tank of petrol or diesel!
Lower Noise Pollution
Yes, we in India are far more resilient to noise pollution than those living in the western world. We have certainly got used to horns blaring and engines roaring, day and night. But that does not mean we enjoy or welcome noise pollution. In fact, quite the opposite!
Though much focus has been on the advantageous of ‘air quality’ with an electric car, just as important, is the benefit of lower noise pollution. In fact, pure electric cars are silent, with an inbuilt ‘sound booster’ to increase road safety for pedestrians.
As our cities in India and across the world become densely populated with cars, the significant negative impact on ‘quality of life’ as a result of increased noise pollution from petrol and diesel vehicles, is just as dangerous, as increased air pollution. Battery-electric cars are a perfect solution in reducing noise pollution and increasing the living standards for us all. Of course, one can only hope that the self inflicted ‘horn blaring’ pollution will also reduce!
Types Of Electric Vehicles (EVs)
“Electric vehicle” is an umbrella term, and a broad one at that. There are a number of different types of electric vehicles (EVs), each with its distinct characteristics and advantages. These include:
- BEVs: Battery-electric vehicles (pure electric)
- PHEVs: Plug-in hybrid electric vehicles (electric and internal combustion engine (ICE) combined)
- MHEVs: Mild hybrid electric vehicles (internal combustion engine (gasoline or diesel) along with regenerative braking)
- FCEVs: Fuel cell electric vehicle (electric with hydrogen as fuel)
The above “types” are powered either entirely or partially by electric energy and have different environmental impacts.
Battery-Electric Vehicles (BEVs)
Battery-electric vehicles (BEVs), also known as pure electric vehicles, are powered entirely by electricity (i.e. the vehicle does not have a conventional internal combustion engine). BEVs have zero-tailpipe emissions and help improve local air quality.
BEVs are also very economical to drive. A BEV can cost as little as Rs 50 per 100 kilometres to drive. Examples of best-selling EVs include, the all-electric Tesla Model 3 and the all-electric Renault Zoe. A BEV is charged by plugging in the electric vehicle to a dedicated electric car charging station (home or public charging stations). BEVs are well suited for those living in towns, cities and urban centres. Of course, battery-electric vehicles are also suitable for those living in rural settings.
Plug-In Hybrid Electric Vehicles (PHEVs)
Plug-in hybrid electric vehicles (PHEVs) differ from battery-electric vehicles (BEVs), in that, PHEVs use both a conventional internal combustion engine (ICE) and an electric engine for propulsion. Plug-in hybrid vehicles combine the advantages of electric driving and internal combustion engine driving.
On shorter distances, the PHEV uses the electric mode to drive emission-free, using the on-board EV battery and regenerative braking. For longer distances, the plug-in hybrid electric vehicles switches to using the internal combustion engine.
With a PHEV, the vehicle can cost as little Rs 50 per 100 kilometres to drive on e-mode, without any tailpipe pollution, and also be driven long-distances, without the fear of range anxiety! Most PHEVs have an EV battery of up to 15 kWh and can achieve a zero-emission electric range of up to 50 kilometres. No wonder PHEVs are fast becoming popular globally, with much potential or India. Like a BEV, the plug-in hybrid electric vehicle is charged by using an external power source (EV charging point) for charging.
PHEVs are suitable for those that drive long-distances on a regular basis but want to lower the negative environmental impact from tailpipe pollution. PHEVs are also suitable for those individuals and families that are seeking to save money by taking advantage of electric driving. The Volvo XC40 PHEV and the Volkswagen Golf 8 are good examples of PHEVs.
Mild Hybrid Electric Vehicles (MHEVs)
Mild hybrid electric vehicles (MHEVs) are a limited form of electric driving. These vehicles also use hybrid technologies (electric driving and internal combustion engine), but the EV battery is much smaller than a BEV or PHEV.
Moreover, in a mild hybrid, the EV battery cannot be charged via an external source (i.e. EV charging station). In a MHEV, the battery is charged by capturing the energy released during braking, a process known as regenerative braking. MHEVs have lower tailpipe emissions, and are more economical to own, run and maintain than petrol and diesel cars.
MHEVs are a better option than a petrol or diesel car, but not as good an option as a BEV or PHEV. Mild hybrids are well suited for those living in regions with limited charging infrastructure. Again, MHEVs have great potential in India, given the limited public EV charging infrastructure.
The Toyota Prius is a good example of a mild hybrid electric vehicle.
Fuel Cell Electric Vehicles (FCEVs)
Fuel Cell Electric Vehicles (FCEVs) also called hydrogen fuel cell vehicles, have a fuel cell stack that uses hydrogen to generate the electricity needed to power the electric vehicle. The fuel cell generates electricity and pure water vapour that can escape via the tailpipe.
It is capable of generating electricity as long as there is a steady supply of hydrogen. Fuel cell electric vehicles can be refuelled with hydrogen at purpose built filling stations. Filling an FEC takes no more than five minutes.
FCEVs have a range of about 500 kilometers or more between refueling. Today, the only and major limitation is the very limited hydrogen refuelling station network globally. The Toyota Mirai FCEV is a good example of this type of EV.
